I have the garmin Varia camera, and have not had any issues with it. I run it at 720 just to help battery life, and the picture quality is really clean. I was surprised, the initial reviews were not that good. It doesn’t what I need it to do.
My only complaint is the mount. The one that comes with it, just isn’t that great, I have had the rubber band type fastener come off on a couple of rides.
